Silver Cinquefoil
Potentilla argentea
Silver Cinquefoil is a perennial herb characterized by the silvery-white felted undersides of its palmately divided leaves. It grows up to 50 cm tall and produces bright yellow flowers with five petals. The species is highly drought-tolerant and typically inhabits sunny, nutrient-poor sites such as dry grasslands, rocky outcrops, or roadsides.
Details
Habitat function
Provides habitat and food for wild bees and butterfly caterpillars in open landscapes.
Nutrient uptake
Low; adapted to nutrient-poor conditions.
Food source for
Nectar source for wild bees (e.g., Andrena species) and host plant for caterpillars (e.g., Pyrgus species).
Human use
Formerly used in traditional medicine as an astringent for diarrhea or inflammations.
Ecology
Ecological role
Pioneer plant on sandy soils; important food source for specialized insects; frequently exhibits apomictic reproduction.
Natural predators
Various insect larvae (e.g., beetles) and grazing by ungulates.
Competitor species
More competitive grasses when site eutrophication increases.
Ecosystem service
Soil stabilization on dry embankments, supporting pollinator biodiversity.
Threats
Eutrophication (nitrogen input) and the abandonment of grazing on dry grasslands (scrub encroachment).
Scientific profile
Profile
Reproduction
Generative via seeds (often apomictic) and vegetative through branching of the rhizome.
Protection & threats
Main threats
Eutrophication via atmospheric nitrogen deposition, succession and scrub encroachment following land abandonment, and direct destruction of nutrient-poor grassland sites by development.
